Finally! Google has released version 4.0 of Chrome for Windows, bringing the much-anticipated extensions framework out of beta and into the stable channel. Currently, more than 1500 extensions are already available. Version 4.0 carries more features than just extensions, though.

Chrome is not able to block ads, it can only hide them after they have been requested, downloaded and decoded. You still get all the tasty cookies from advertisers and you still have to bear with badly written sites which cause the engine to block while waiting for some advertisement or tracking server to respond. Chrome simply lacks the necessary APIs.
